Interesting article on diffraction by Roger Cicala.

For those with f/entekaphobia (fear of f/11) it is interesting to note that f/11 was generally as sharp or sharper than f/4 and f/16 compared favorably to f/2.8. He tested with two Zeiss 50mm lenses and a Nikon 50mm f/1.4G.

Thanks, Robin, this is interesting indeed and one learns about the cameras just as much as about the lenses.  I shoot quite a bit of macro and have often found that f/16 is not a problem, especially on lenses like the 200mm f/4 which seem optimized for the smaller openings.
